Abstract (en)
[origin: WO03076681A1] The invention relates to a device for hot dip coating metal strands (1), particularly strip steel, in which the metal strand (1) can be vertically guided through a reservoir (3), which accommodates the molten coating metal (2), and though a guide channel (4) connected upstream therefrom. An electromagnetic inductor (5) is mounted in the area of the guide channel (4) and in order to retain the coating metal (2) inside the reservoir (3), can induce induction currents in the coating metal (2) by means of an electromagnetic traveling field. While interacting with the electromagnetic traveling field, said induction currents exert an electromagnetic force. The inductor (5) has at least two main coils (6) that are arranged in succession in movement direction (X) of the metal strand (1), and has at least two correction coils (7) for controlling the position of the metal strand (1) inside the guide channel (4) in direction (N), which is normal to the surface of the metal strand (1). These correction coils are also arranged in succession in movement direction (X) of the metal strand (1). In order to improve the efficiency of the control of the metal strip inside the guide channel, the invention provides that at least a portion of the correction coils (7), when viewed in movement direction (X) of the metal strand (1), are arranged so that they are offset with regard to one another perpendicular to movement direction (X) and perpendicular to direction (N) that is normal to the surface of the metal strand (1).
